Dear 20th Century Fox Board of Directors,
The Fantastic Four's film rights belong at Marvel and Disney for the following reasons:
1) The most recent film flopped miserably.
This movie made only 168 million dollars , which is actually a lot less money than its predecessors made( Fantastic Four and Fantastic Four: Rise of the Silver Surfer made 331 million dollars and 289 million dollars, respectively).Do you really want to hold the rights to this franchise ?
Not only did this film flop like a dying bird at the box office, but it was a critical failure.
2) Strike 3, you're out.
You have had not one, not two, but three chances to make a good and successful movie featuring these characters, and you have failed again and again. Marvel deserves a shot at redeeming the franchise.
3) At least you have the X-Men and Deadpool.
Though the Fantastic Four franchise is a mess, at least you have the rights to the X-Men and Deadpool. With franchises like the X-Men film series, you simply don't need the film rights to the Fantastic Four.
4)Giving (or sharing) these rights to( or with) Marvel will be very good for the company.
As we all know, Sony and Marvel recently made a deal to share Spider-Man's film rights. If you and Marvel made a similar deal, both of you will share the profits made by a Marvel Studios-produced or coproduced film. Remember that Marvel can make a lot of money from anything that has their name on it.
I hope that you will read this and consider how sharing the rights with Marvel will benefit your company, Marvel, and millions of comic book fans.
P.S: X-Men: Days of Future Past was awesome. Can't wait for Apocalypse!
